ALLAN K. BOWMAN, or PITrsBURG, PENNSYLVANIA:

. To all it mayponCem'; a

Be it known that I, ALLAN' K. BOWMAN, acitizen of the United States, and a resident of Pittsbur in the county of-Al'legheny and 5 State of llennsylvania, have invented a new and Improved Pipe, of which the following is a full, clear, and exact'description.

My invention resides incertain new and useful im rovements in tobacco pipes, ob-

. of this character which will arrest the nicotin and otherpoisonous matter from the to? bacco before reaching'the mouth; collect and confinethe saliva as well as the residue from the bowl; cooling-thesmoke and the stem smoke is assured, and to provide for the uniform burning of the tobacco within'the bowl as by effecting acentral draft therein. These objects and othersIare-acoom lished by y invention, Ione'embodiment 0 which is hereinafter disclosed,

' 1 L -Reference is-to be had-to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate correspondingparts in both the fig- Figure,1 is a central-vertical section with the referred type of my improvement appliecl. to a straight-stemmed pipe Fig. 2 is a side view artly in central, vertical section, ofa curvegstempipe embodyin my. inven- .-tion .;"Fig. 3fillustrates a mod' ed formof stem differing from those shown in Figs. 1

In either case the stem portion 2 of'the' owl is counterbored from its outer end to provide a chamber3, which has an aperture 4 passing through the bottom of the stem, serving as an I air intake. opening. The outer end of this chamber 3 is interiorly threaded for receiving an exterior-ly th'r'eaded plug -5 the latter hav- -j is unobstructed.

.ing' a central [a 'erture through which is passed a tube 6 eading to the bowl of the pipe at a point substantially at its center and providing a smoke-way. The tube. 6, as shown, isformed slightly tapered with an en.- larged head7 which plug 5, whereby as it 1s inserted within the plug and pushed to the'inward limit of its movement, it will be frictionally retained in positio The 0 chamber 3 into t e bowl of the pipe is, as

"shown, to'be ofsufficient diameter to .pro-' vide. an annular space surrounding the tube 6 when the latter is 111 place, whereby the. air

in its passage through the aperture 4 to the chamber and thence to the bowl of the pipe,

. The projecting end of the plug 5 from the stem lportion 2 of the'bowl 1s preferably of slight increased diameter, to provide a shoul er which limits the extent to which the lug ma be threaded in the direction of the bowl. This enlarged portion of the lug receives the detachable stem portion 8 of the pipe, which ma be either straight or curved, and is enlarge and counterbored to form a reservoir 9, the end wall'of which is preferably provided with a nipple 10 in central alinement with the aperture in the stem 8 "and the tube 6:

, In Fig. 3 I have shown the stem or bit of the .pipe made in two pieces, the counterbored portion of which providing the reservoir 9, being in threaded engagement with the mouth-piece. I A

Fi 4'shows the airintake o' ,ening 4 provide with a ball valve 4, which operates toclose said opening at the intervals when there is no'suction through the stem. At

each puff of the smoker the ball lifts and permits the air'to pass as in that form of my invention shown in Figs. 1 and 2. The valve may be'found desirable in instances to revent the fire from dying out in the bow In the use of the-pipe, as the smoker draws through the stem, a quantity of air is drawn throughthe top'of the bowl as is usual, and

is placed adjacent to the ening leading from the an additional quantity passes through the aperture or air intake opening 4 into the amber 3 and thence into the bowl of the pipe around the extremity of the tube 6,

operating to prevent the tube and stem 2 from becomi heated and thereafter mixing rendering the taste.

Such residue as passes through thertube or tube passing to substantially the center of smoke chamber in the direction of the mouth will be collected and retained within thereservoir 9. This reservoir will obviously also collect the saliva passing from the mouthtrated and described, that 'the pipe may be easily disassembled as by unscrewing the displaceable stem 8, ermitting the reservoir 9 to be emptied and and cleaned.

The construction described, although being the preferred embodiment of my invention,

.. is, nevertheless, susceptible of numerous -cl aims annexed.

modifications falling within the scope ofthe Having thus described invention-I claim as new and desire. to secure by Letters Patent 1. A. pipe having a'chamber formed in .the

stem thereof provided with an air intake opening, and a tube assihg throu h said amberto the bowl 0' the me, said chamber communicatin with t pipe around said tu e.

the tube 6 withdrawn e bowl of the f L 2. A pipe'having a chamber formed in the stem thereof communicating with the bowl of the pipe and provided with an air intake 0 ening, and a tube passing through said ciiamber to the bowl of the pipe substantially at the bottom center thereof.

,3. Apipe havin a chamber formed in the stem provided wit an air intake opening, a plug carried by the stem,- and a tube'passin through the plug and chamber to the bow of the pipe.

4. A pipe having a chamber'formed in the integral stem ortion thereof communicating with the bow and rovided with an air intake o'ening, a disp aceable stem connected to sai integral stem portion having a reser- .voir, and a tube passing from said reservoir throu h said chamber to the bowl of the pipe.

5. g pipe having a reservoir formed in the stem thereof, and a removable tube provid-' ing communication between said reservoir and the bowi of the pipe.

l 6. A pipe having a chamber provided with an air intake opening and a'reservoir formed in the stem thereof, and means passing through said chamber providin communication between the reservoir an the bowl of the pipe.
